Radar scanning system for static obstacle detection for power door movement

A vehicular door control system responsive to object detection includes a radar unit disposed at a vehicle that has a field of sensing adjacent to and exterior a door of the vehicle and that transmits radar signals and receives reflected radar signals representative of an object. A scanning actuator coupled to the radar unit moves the radar unit relative to the door to create a variation between the transmitted radar signals and the reflected radar signals. An electronic control unit (ECU) operates the radar unit to transmit the radar signals. While the radar unit is transmitting the radar signals and receiving the reflected radar signals, the ECU operates the scanning actuator to move the radar unit relative to the door. The ECU processes the received reflected radar signals to determine presence of the object and operates an electrically powered actuator coupled to the door to open and close the door.
